The paper presents the development of metal vapor active element with two energy sources. The first source provides the required vapor pressure of the work substance; the second source is used to pump active media. The resonant inverter was used for the inductive dispenser heating. The paper considers the design of the active element and the pilot plant which operability confirmed by waveforms of generation, current and voltage of a gas discharge tube. The inductive dispenser is used as a vaporizer of the working substance - metal atoms.

In this work, using the RHEED technique, the optimal stage of sapphire nitridation completeness was determined taking into account the electron beam influence on a nitridation process. It was found that as a result of the sapphire surface nitridation at the optimum stage of completion the A1N crystalline phase about one monolayer is formed on the surface. The A1N buffer layer growth under conditions of optimal stage of nitridation process completion is characterized by a smooth surface morphology and better crystalline perfection compared to A1N growth without nitridation or with excessive sapphire nitridation.

Downstream data transmission in an optical network is performed by broadcast transmission, whereas upstream transmission must use bandwidth allocation algorithms to prevent data packets from colliding. Such scheduling algorithms must comply with the multipoint management Protocol defined in the IEEE 802 standard. A number of bandwidth allocation algorithms are known for optical networks. The purpose of this work is to compare several existing algorithms, such as UPCF, Min, and RDM (Russian Doll Model). The algorithms are modeled using a discrete event simulator implemented using the C language and developed specifically for the study of GPON networks that provide different classes of service in each optical network block. Based on the analysis of the simulation results, proposals are formulated for using each of the algorithms for the required combinations of service classes.

Computer simulation of the dustiness in the blind drift of coal mine was carried out. The most probable scenario for the occurrence of dustiness in the blind drift of coal mine, during the operation of mining combine, connected with the shutdown of the irrigation system due to clogging of nozzles, is determined. In this case, the determining factor affecting dustiness is the ventilation mode of operation and the associated air flow rate in the mine. The Fire Dynamics Simulator (FDS) software package of computational fluid dynamics is proposed to be used. The calculations were performed using the Large Eddy Simulation (LES) turbulence model, in the approximation of low Mach numbers (Ma <0.3)(subsonic approximation), the Deardorff model for calculating of the turbulent viscosity, and the model based on the discrete-path Euler-Lagrange method for describing of the two-phase flow. Analytical dependencies and initial data for modeling were determined: geometric parameters of the blind drift, ventilation and dust emission parameters, dispersed dust composition, initial conditions. The adequacy of the computer model developed was verified on the basis of experimental data obtained by testing the dynamics of dust aerosols at the test bench – "MGU Shakhtpozhservice" LLC. The adequacy of the developed computer model is confirmed based on satisfactory agreement of the simulation results with experimental data. The results of dustiness modeling in the blind drift were analyzed. The distribution of the coal dust mass concentration over the blind drift cross sections for various air flow values of 2.4, 3.6 and 4.8 m3/s is shown. The concentration of coal dust in the area of local ventilation fan jet action is significantly higher – up to 1.8 g/m3 for suspended dust than in the translational movement zone with permissible value of 150 mg/m3. The dependences of the concentrations for suspended and precipitated coal dust along the length of the blind drift were obtained. As a result of dispersed composition analysis, the following were established: the main maxima of the suspended particles size distribution functions by mass correspond to particle diameters of 5-7 microns, in addition, particles with diameters from 20 to 40 microns constitute a significant proportion; significant dust deposition with a diameter of more than 50 microns.

We show an experimental study of superconducting X-mon qubit based on low noise wideband measurement setup. The setup includes wide stop-band low frequency filters with a stopband frequency up to 13 GHz, the broadband low-noise cryogenic microwave amplifier (cLNA) operating at 3.8 K. The obtained power dissipation of the cLNA is below 20 mW, the frequency operating ranges from 6 GHz to 12 GHz with a gain of 30 dB. The equivalent noise temperature of the amplifier is bellow 6 K for the presented frequency range. We demonstrate here the characterization of the superconducting X-mon qubit coupled to an on-chip coplanar waveguide resonator. We show standard qubit experiments: one and two-tones qubit spectroscopy, ac-Stark shift experiments for probing and excitation power sweeps.

The widespread use of induction motors (IM) for domestic and industrial purposes is determined by a simple and clear structure. The complexity of the development and production of energy-saving soft-start structures for high-voltage IM is relevant due to the presence of deep voltage drops in the mains caused by large starting currents with direct connection. Currently, resistive and frequency start-up circuits are used. Multi-zone regulation is based on the principle of a smooth increase in power supply. In this paper, we propose an algorithm for limiting the starting current of induction motors and a method for developing a soft starter of induction motors based on a multi-zone transistor AC voltage regulator (RAV) by means of electromagnetic process analysis.
